Import Board Connector — Buy in wholesale FOB from Supplier in China

The 0.635mm pitch board-to-board connector from Yuliang Electronics Co., Ltd. is a surface-mount female connector manufactured in Dongguan, Guangdong. It carries the CYLCONN brand and is built for industrial automation environments with an operating temperature range of -30°C to 80°C. The housing uses LCP material rated UL94V-0, while terminals employ copper alloy with phosphor bronze contacts finished in gold plating. Current rating is 0.5A, with insulation resistance of 100M Ohms minimum and dielectric withstanding voltage of 200V per minute. Contact resistance is specified at 20m Ohms maximum initially, rising to 50m Ohms maximum in final condition.

The connector uses SMT mounting and is available in pin positions ranging from 30 to 80 pins, with pin length customizable to customer design. LCP (Liquid Crystal Polymer) was selected for the housing due to its excellent thermal stability and dimensional accuracy during reflow soldering, a standard requirement for fine-pitch SMT components. The gold plating on phosphor bronze contacts provides reliable contact resistance and corrosion resistance, which is typical for industrial-grade connectors subject to repeated mating cycles. Copper alloy terminals offer a balance of conductivity and mechanical strength. The brown coloration of the housing is a visual differentiator and does not affect electrical performance.

This connector suits industrial control systems, power systems, household appliances, communication equipment, and automotive wiring applications. Yuliang Electronics produces over 10,000 connector types that substitute for Molex, JST, TYCO, AMP and JAE products, indicating broad interoperability for buyers seeking second-source options. The company accepts OEM and ODM designs with flexible order quantities. Packaging options include PE bags, tape and reel, tray, PVC and plastic tube. Buyers should confirm minimum order quantities, exact lead times and payment terms directly with the supplier, as these vary with order quantity and customization requirements.
